This study developed and evaluated a novel transferosomal gel formulation incorporating luliconazole to enhance topical antifungal therapy. Luliconazole, an imidazole antifungal drug, is widely prescribed for dermatophytic infections such as tinea pedis, tinea cruris, and tinea corporis. However, conventional topical formulations often suffer from poor skin penetration, low drug bioavailability, and the need for frequent application, which may reduce patient compliance.
In this work, transferosomes were prepared using thin film hydration with lecithin and Tween 80 at varying concentrations, followed by incorporation into a carbopol gel base. The transferosomes demonstrated high entrapment efficiency of 74.45% and 92.75% with particle sizes ranging between 60–200 nm, and scanning electron microscopy confirmed their spherical morphology. The in vitro release study revealed an inverse relationship between entrapment efficiency and release rate, indicating a controlled and sustained release behavior.
The formulated transferosomal gel was further characterized for pH, drug content, spreadability, and viscosity, all of which fell within acceptable ranges for topical application. Importantly, antifungal activity testing confirmed that the luliconazole transferosomal gel exerted a strong therapeutic effect against dermatophytes.
Overall, the study highlights the potential of transferosomal technology to overcome the limitations of conventional antifungal formulations. By improving drug penetration and sustaining drug release, the luliconazole transferosomal gel reduces the frequency of application required, which may enhance treatment adherence and patient outcomes. These findings underscore the promise of transferosome-based gels as a novel drug delivery strategy for managing dermatophytic skin infections effectively.
